They can +copy resources into the resource area through the publication step, +and move them back through a recover step. Authors do not have direct +write-access to their resource space. + +During the publication step, several events will be +triggered. Metadata is gathered, where a wizard manages default +entries on a hierarchical per-directory base: The wizard imports the +metadata (including access privileges and royalty information) from +the most recent published resource in the current directory, and if +that is not available, from the next directory above, etc. The Network +keeps all previous versions of a resource and makes them available by +an explicit version number, which is inserted between the file name +and extension, for example C, while the most recent +version does not carry a version number (C). Servers +subscribing to a changed resource are notified that a new version is +available. + +=head1 DESCRIPTION + +B takes the proper steps to add resources to the LON-CAPA +digital library. This includes updating the metadata table in the +LON-CAPA database. + +B is many things to many people. + +This module publishes a file.
